Primary adrenal lymphoma discovered as an incidentaloma: case report and review of the literature

Abstract

Primary adrenal lymphoma (PAL) discovered at an early stage is extremely rare. We report a case of PAL incidentally discovered by abdominal computed tomography (CT) scan as a 4.5-cm solid mass in the left adrenal gland. The patient was an 80-year-old man, and, from imaging studies, the left adrenal mass was considered to be a non-functioning adrenal cortical cancer. Left adrenalectomy was performed, and the resected tumor proved to be non-Hodgkin's lymphoma of diffuse large B-cell type. Adjuvant chemotherapy was administered, and the patient has been well with no evidence of the disease for 20 months postoperatively.
